BELTING.

To all whomt may concern:

Be it known that I, ALEXANDRE M. GREAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improveis a specification.

The present invention relates to belting of the general character andfor the purposes of that disclosed in my patent, No. 1,183,869, May 23,i916.

The object is to provide ak strong, {iexible, and at the same time,relatively inexpensive article that may be manufactured in substantiallyany length desired, and from which portions or sections may be cut forindividual use.

In the accompanying drawings,

Figure 1 is a view in elevation of one side of a portion of a length ofbelting constructed in accordance with the present invention.

Fig. 2 is a similar view of the opposite side.

Fig. 3 is a cross sectional view, and

Fig. 4 is a cross sectional view somewhat diagrammatic in its character,showing the elements separated to more clearly illustrate theconstruction and relation thereof.

`F ig. 5 is a detail view of a portion of the finished material whenlaid out straight.

Similar reference numerals designate corresponding parts in all thefigures of the drawings. i

In the Vembodiment disclosed, a casing strip 5 of woven flexiblematerial is employed, the longitudinal marginal portions 6 of said stripbein doubled inwardly toward each other, this strip thus producing acasing, the edges 7 of the strip preferably meeting centrally andforming a longi-v tudinal joint.

Within the casing thus produced, is located a reinforcing strip 8 alsoof woven material, which ispreferably coarser and stiffer, a suitablefilling being employed in said strip 8 to produce the desired stili'-ness.

Extending longitudinally along one side of the casing strip and bridgingthe joint between the edges 7,.is a tape 9, also of woven material, thistape being secured in n y Specification of Letters Patent.

place by suitable means, as for example, a zigzag line of stitching 10,which passes through the tape 9, the margin 6, the central portion ofthe reinforcing strip 8 and the opposite wall or body of the casingstrip 5.

The belting thus produced is shaped to have permanent transversecurvature, and the margins are made longer than the cen tral portion. Inits construction the preferable method is to associate and secure thevarious parts together, and afterward produce the said curvaturev byinoistening the belting and shaping the same between heated dies. One ofthese dies is a round block having a transversely curved surface, andthe coperating die has a reversely shaped mating surface. The materialwhen pressed between said dies has its side margins stretched or madelonger than its intermediate part, thereby producing the transversecurvature. It will be understood that other methods may be employed.

From the foregoing, it is thought that the construction, operation andmany `advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and vit will beunderstood that various'changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. As an article of manufacture, a length of belting, comprising acasing strip of flexible material having its side margins turnedinwardly toward each other, a reinforcingV strip located within thecasing thus formed, and a line of zig-zag stitching passing through theedges of the strip and through the intermediate portions of thereinforc- -ing strip and bridging the joint formed by strip locatedWithin the casing thus formed, and longer than the intermediate portionof and means securing the inturned longithe reinforcing strip. 1Gtudinal edges of the casing strip and the In testimony whereof, I afX mysignaintermediate portion of the reinforcing ture in the presence of tWoWitnesses.
